As New York mayor, Rudy Giuliani billed obscure city agencies for tens of thousands of dollars in security expenses amassed during the time when he was beginning an extramarital relationship with future wife Judith Nathan in the Hamptons, according to previously undisclosed government records.

The documents, obtained by Politico under New York’s Freedom of Information Law, show that the mayoral costs had nothing to do with the functions of the little-known city offices that defrayed his tabs, including agencies responsible for regulating loft apartments, aiding the disabled and providing lawyers for indigent defendants.

At the time, the mayor’s office refused to explain the accounting to city auditors, citing “security.”

See? Even if it makes no sense at all, just say you can’t comment on it because the terrorists would win. Here is a leader with the strength to invoke “state secrets” or “executive privilege” without batting an eyelash, which is just what the Republicans are looking for.

Rudy certainly is building a compelling case for himself as Dubya’s Mini-Me.
